Abstract
A metal furnace header gate system haying a recirculation port in the furnace, a hot gas generator, a gas blower, and a furnace door. The door has an embedded gas manifold and outlet ports that each connect the manifold to a directional nozzle. The blower draws exhaust from the recirculation port into the hot gas generator, which generates additional exhaust and mixes the exhaust gases together. The blower forces this exhaust mixture into the manifold, through the nozzles, and into the furnace. A computer controls the blower and the hot gas generator to regulate the system.
Claims20
A header gate system for a metal recycling furnace, said furnace having a delacquering chamber with a doorway opening into said delacquering chamber, said furnace having an exhaust hood positioned proximate said delacquering chamber, said exhaust hood collecting exhaust gases from said delacquering chamber, said header gate system comprising:
- a. a door adapted to close at least in part said furnace doorway, said door having an inner face directed into said furnace when said door is positioned in said doorway, said door having a gas inlet port and a gas outlet port, said outlet port being positioned on said door inner face;
- b. a door frame positioned in said furnace doorway, said door frame adapted to receive and mate at least in part with said door;
- c. a recirculation port, said recirculation port opening into said delacquering chamber and providing a path for exhaust gases to exit said delacquering chamber;
- and
- d. a gas propelling device in gaseous communication with said recirculation port and said door inlet port, said propelling device drawing exhaust gases from said recirculation port, and urging said exhaust gases into said door inlet port and out said door outlet port.
A header gate system for a metal recycling furnace, said furnace having a delacquering chamber and a melt chamber, said furnace having a doorway opening into said delacquering chamber, said header gate system comprising:
- a. a door adapted to close at least in part said furnace doorway, said door having an inner face directed into said furnace when said door is positioned in said furnace doorway, said door having a gas inlet port and a gas outlet port, said outlet port being positioned on said door inner face;
- b. a door frame positioned in said furnace doorway, said door frame adapted to receive and mate at least in part with said door;
- c. a recirculation port, said recirculation port opening into said one of said delacquering chamber and said melt chamber, said recirculation port providing a path for exhaust gases to exit said one of said delacquering chamber and said melt chamber;
- and
- d. a gas propelling device in gaseous communication with said recirculation port and said door inlet port, said propelling device drawing exhaust gases from said recirculation port, and urging said exhaust gases into said door inlet port and out said door outlet port.
A header gate system for a metal recycling furnace, said furnace having a delacquering chamber and a melt chamber, said furnace having a doorway opening into said delacquering chamber, said furnace having an exhaust hood positioned proximate one of said delacquering chamber and said melt chamber, said exhaust hood collecting exhaust gases from said one of said delacquering chamber and said melt chamber, said furnace having a computer control system, said header gate system comprising:
- a. a door adapted to close at least in part said furnace doorway, said door having an inner face directed into one of said delacquering chamber and said melt chamber when said door is positioned in said furnace doorway, said door having a gas inlet port and a gas outlet port, said outlet port being positioned on said door inner face;
- b. a door frame positioned in said furnace doorway, said door frame adapted to receive and mate at least in part with said door;
- c. a recirculation port, said recirculation port opening into said exhaust hood, said recirculation port providing a path for exhaust gases to exit said exhaust hood;
- d. a hot gas generator, said hot gas generator having a gas inlet and an exhaust gas outlet, said gas inlet being connected to and opening into said recirculation port, said hot gas generator collecting exhaust gases from said recirculation port, generating hot exhaust gases, and creating an exhaust gas mixture of said generated hot exhaust gases and said exhaust gases from said recirculation port;
- and
- e. a gas propelling device in gaseous communication with said hot gas generator exhaust gas outlet and said door inlet port, said propelling device drawing said exhaust gas mixture from said hot gas generator through said exhaust gas outlet, and urging said exhaust gases into said door inlet port and out said door outlet port.
